Answer:
Planter 1 is 48 meters cubed
Planter 2 is 24 meters cubed
Total volume = 72
Step-by-step explanation:
The formula for the volume of a rectangular prism is length times width times height. So, 4*4*3. This equals 48. If the other planter is half the volume, divide 48 by 2 to get 24 meters cubed. To find the total area add both results to get a total of 72 meters cubed.
Answer:
42.9%
Step-by-step explanation:
-42.857142857142854 is the exact number. Rounded to 42.9% thus b: is the correct answer.
Formula:
[(120 - 210) / 210] × 100% = -0.42857142857142855 × 100% = -42.857142857142854%
Answer:
Both are wrong.
Step-by-step explanation:
We have that:
Both decomposed the fraction
into a sum of fractions. Whoever's decomposition sum has a value of
is correct.
David:

, which means that David is wrong.
Patti

, which means that Patti is wrong.
So the answer is that both are wrong.
Answer:
D. 11.8 cm
Step-by-step explanation:
This triangle is a 30°-60°-90° triangle. There is a shortcut to find the lengths of the sides of a 30°-60°-90° triangle. The longest side is the hypotenuse. The longest side is double the shortest side or, the shortest side is half the longest side. Here the longest side is 5, so the short leg (shortest side) is 2.5
The other shortcut is that the longer leg is the
short leg×sqroot3
Here, the short leg is 2.5, so the long leg is 2.5×sqroot3
Perimeter is all the sides added together.
5 + 2.5+ 2.5×sqrt3
Do the times first.
5 + 2.5 + 4.3
= 11.8
